Integration of Europe was started when European Union Treaty was concluded at Maastricht for the first time on December, 1991. Europe which may be called as a cradle of modern national state has realized a single Europe not only in the socio-economic integration field but also in the political field. Under this background, it is considered that life-long education policy for developing a new integrated growth engine of EU requires educational response that may get ready for socio-economic environmental transformation more than anything else. In particular, this policy is faced with an important task of having to achieve harmony of efficiency through diversity and mutual coordination in pursuing cooperation and integrated development of life-long education field. However, notwithstanding their efforts, since 2008, some countries of EU were faced with economic crisis due to economic recession and this situation starts to drive the whole Europe even to the point of their financial crisis at last. This crisis is currently shaking socio-economic integration of EU. This study intends to observe a status of establishing life-long education system and promoting a policy for socio-economic integration of EU and to analyze as to what kind of relevance adult participation rate of life-long learning among the countries belonged to EU has with per capita income and to explore as whether socio-economic integration among member countries could be sustained based on problems of integrative life-long education system under the economic crisis of EU. In addition, through this study, an implication required for presenting a new paradigm conversion, policy establishment and development direction for the life-long education of our country is intended to be deduced.

A recent rapid change in society drives the colleges and universities into the unlimited competition for satisfying users' demand. The introduction of customized educational system is one of the survival strategies of university that reflected this characteristic. The result of a research on the customized curriculum of the dental hygiene study shows that the managers of dental hospitals and clinics think that the dental assistance field is dental hygienist's major task. On the other hand, though the dental hygienists think that the oral health education is the main task, they just comply with the intention of managers of the dental hospitals and clinics in reality. Hence, the reinforcement of the practicum in the industry field is required to meet the demand from the industry. And there is also a need to offer an opportunity of self-realization through work life by allowing dental hygienists to have stable status within dental hospitals and clinics with enhanced education and training on preventive dental treatment and oral health.

We simulated the fault reactivation experiment conducted at 'Main Fault' intersecting the low permeability clay formations of Mont Terri Underground Research Laboratory in Switzerland using TOUGH-FLAC simulator. The fluid flow along a fault was modelled with solid elements and governed by Darcy's law with the cubic law in TOUGH2, whereas the mechanical behavior of a single fault was represented by creating interface elements between two separating rock blocks in FLAC3D. We formulate the hydro-mechanical coupling relation of hydraulic aperture to consider the elastic fracture opening and failure-induced dilation for reproducing the abrupt changes in injection flow rate and monitoring pressure at fracture opening pressure. A parametric study was conducted to examine the effects of in-situ stress condition and fault deformation and strength parameters and to find the optimal parameter set to reproduce the field observations. In the best matching simulation, the fracture opening pressure and variations of injection flow rate and monitoring pressure showed good agreement with field experiment results, which suggests the capability of the numerical model to reasonably capture the fracture opening and propagation process. The model overestimated the fault displacement in shear direction and the range of reactivated zone, which was attributed to the progressive shear failures along the fault at high injection pressure. In the field experiment results, however, fracture tensile opening seems the dominant mechanism affecting the hydraulic aperture increase.

Recently, in order to reduce the time required to replace an optical jumper cord, many researchers are using a field-installable connector and applying the ferrule polishing method, ferrule mechanical contact method, or ferrule fusion contact method. However, the process of arranging the length of the optical fiber, i.e., inserting the optical fiber into the ferrule by hand and checking its cross section, takes 60% of the time required for the entire process, which increases the overall cost. Therefore, in order to make this task more cost-effective, we will develop an automated inspection system with automatic cross-sectional arrangement of a field-installable connector. This system will be able to decrease the failure rate from 10% to 2% compared with the conventional method when cutting the optical fiber inserted into the ferrule. It will also improve the productivity by decreasing the test time by 28% compared with the conventional method. Our studies showed that it was possible to reduce the production costs and improve the quality of a field-installable connector, and we expect it to dominate the market.

The purposes of this study were to identify the characteristics of students with different cognitive styles in the communication process according to the types of mathematical tasks and investigate the effects of their cognitive styles and types of mathematical tasks on their mathematical communication. For this, the investigator selected subjects according to the field dependent-field independent cognitive style by Witkin et al.(1977, p. 7). Mathematical tasks were developed in the areas of numbers and operations, regularity, and measurement according to the four types of Stein & Smith(1998, p. 269), which include the Memorization, Procedures without Connections, Procedures with Connections, and Doing Mathematics tasks. The selected students were divided into homogeneous groups according to their cognitive styles, and their communication processes according to the four types of mathematical tasks were observed through participation and videotaped. The videotapes were then transcribed and analyzed in protocols. The conclusions is that mathematical tasks of high cognitive level had positive effects on the activation of significant mathematical communication among the students and that differences in approaches to tasks according to their cognitive styles influenced their communicative activities in speaking and listening.

A trend analysis of research articles in a field of knowledge is significant because it can help in finding out the structural characteristics of the field and the future direction of research through observing change in a time series. We identified the structural characteristics and trends in text data (keywords) gathered from research articles which in itself is an important task in various research areas. The titles and keywords were crawled from research articles published from 2016 to 2018 in the Research Journal of the Costume Culture (RJCC), one of the representative Korean journal in the field of clothing and textile. After we extracted data comprising English titles and keywords from 195 published articles, we transformed it into a 1-mode matrix. We used measures from network analysis (i.e., link, strength, and degree centrality) for evaluating meaningful patterns and trends in the research on clothing and textile. NodeXL was used for visualizing the semantic network. This study observed change in the clothing and textile research trend. In addition to covering the core areas of the field, the subjects of research have been diversifying with every passing year and have evolved onto a developmental direction. The most studied area in articles published by the RJCC was fashion retailing/consumer psychology while aesthetic/historic and fashion industry/policy studies were covered to a more limited extent. We observed that most of the studies reflecting the identity of RJCC share subject keywords to a significant extent.

In order to identify the latest research trends using data related to national R&D projects and to produce and utilize meaningful information, the application of automatic classification technology was also required in the national R&D information service, so we conducted research to automatically classify and recommend research field. About 450,000 cases of national R&D project data from 2013 to 2020 were collected and used for learning and evaluation. A model was selected after data pre-processing, analysis, and performance analysis for valid data among collected data. The performance of Word2vec, GloVe, and fastText was compared for the purpose of deriving the optimal model combination. As a result of the experiment, the accuracy of only the subcategories used as essential items of task information is 90.11%. This model is expected to be applicable to the automatic classification study of other classification systems with a hierarchical structure similar to that of the national science and technology standard classification research field.

The great development of the modern science enables the information technology including computer to be promoted, which has the great effects on the whole design field. Most of all, the computer has the feature to express the mathmatical formular through the logic and system, which is being used very efficiently in the design work. CG application to the two-dimensional design may be limited in promoting the basic ability synthetically through the direct and molding experience for its attribute, however, it is possible to create the effects on the different level in addition to those from the traditional skill. In particular, we should keep the fact in mind that the CG application in the design field will be able to accomplish the object only under understanding the attributes and functions for it to have. We should carry out the task to agree with. First, it is necessary to develop the various study on the educational environment to make the process to solve the problems and to promote the effects of the educational media in teaching design with the CG application. This study would make plans to approach that the computer can be utilized for the main method to create design despite of being limited in some point. Moreover, it suggests the possibility for the CG application in the course of building up and motiving the models by applied the basic system, which enables the computer to be applied centering around the composition of geometry pattern of the basic course of the two-dimensional design.

Choosing the best-performance materials is a crucial task for the successful completion of a project in the construction field. In general, the process of material selection is performed through the use of information by a highly experienced expert and the purchasing agent, without the assistance of logical decision-making techniques. For this reason, the construction field has considered various artificial intelligence (AI) techniques to support decision systems as their own selection method. This study proposes the application of a systematic and efficient support vector machine (SVM) model to select optimal exterior materials. The dataset of the study is 120 completed construction projects in South Korea. A total of 8 input determinants were identified and verified from the literature review and interviews with experts. Using data classification and normalization, these 120 sets were divided into 3 groups, and then 5 binary classification models were constructed in a one-against-all (OAA) multi classification method. The SVM model, based on the kernel radical basis function, yielded a prediction accuracy rate of 87.5%. This study indicates that the SVM model appears to be feasible as a decision support system for selecting an optimal construction method.

Reduction and prevention of human error is one of the major interests for the enhancement of system safety and availability in Nuclear Power Plants (NPPs). As human beings have become the weak point in the system safety, a systematic evaluation on human performance during emergency situation should be performed in advance to identify the potential vulnerability of human tasks. Though the data gathering and analysis from real field is an important precondition, there were no available data in nuclear field of korea. This paper presents the result of human performance analysis on emergency tasks in NNPs. Firstly, a task analysis was performed to identify the characteristics of operator tasks during emergency condition and to classify them into a set of generic emergency tasks. Secondly, simulation data were collected and analyzed for the emergency tasks using the full scope simulator of Younggwang NPPs. The analyzed human performance information cover the event diagnosis time, the execution time of each procedural step, observation parameters, typer of irrelevant response, pattern of communication among staffs, and so on. These performance data would be used for human reliability analysis and the research of human error as technical bases.
